9. Censors had been elected the previous year, Sextus Aelius Paetus and Gaius Cornelius Cethegus.¹ Cornelius closed the lustrum.² [2] The number of citizens rated was one hundred forty-three thousand seven hundred four.³ There were great floods that year, and the Tiber overflowed the flat parts of the City; around the Porta Flumentana certain buildings even collapsed and fell. [3] Also, the Porta Caelimontana was smitten by a thunderbolt and the wall in several places round about was struck by [p. 25]lightning; [4] and at Aricia, at Lanuvium and on the Aventine⁴ there were showers of stones; it was also reported from Capua that a great swarm of wasps had flown into the forum and settled in the temple of Mars; the wasps, it was said, were carefully collected and consumed by fire. [5] By reason of these prodigies the decemvirs were directed to consult the Books,⁵ and a nine-day sacrifice was performed, a supplication proclaimed, and the City purified. [6] At the same time a shrine to Victoria Virgo near the temple of Victory was dedicated by Marcus Porcius Cato, two years after he had vowed it.⁶

[7] In the same year a Latin colony was established at Castrum Frentinum⁷ by the triumvirs Aulus Manlius Volso, Lucius Apustius Fullo and Quintus Aelius Tubero; by the law of the last-named the colony was created. Three thousand infantry and three hundred cavalry joined it, a small number in proportion to the size of the tract. The allotments of land could have been thirty iugera per infantryman and sixty per cavalryman. [8] At the suggestion of Apustius one-third of the land was reserved, whereby they were enabled later to enroll new colonists if they saw fit. Twenty iugera were given to each infantryman, forty to each cavalryman.
